# shows a hamster sitting on an wedge-shaped block. The block, in turn, rests on a spring scale. An extra-fine lubricating oil having is sprayed on the top surface of the block, causing the hamster to slide down. Friction between the block and the scale is large enough that the block does not slip on the scale. What does the scale read, in grams, as the hamster slides down?

The hamster slides down in scale is about

See the step by step solution

## Step 1: Given information

mass of hamster

mass of the block

Angle of wedge block

## Step 2: Explanation

The hamster accelerates down the block with

The vertical component of this acceleration is:

So the downward force exerted by the hamster on the block and thus onto the scale is

The net force exerted by the hamster on the block and thus onto the scale is

Therefore, the net force in gram can be calculated as

Therefore, the hamster slides down in scale about
